A brief description of the natural wastewater systems used to handle the institution’s wastewater:

Most wastewater is discharged to a sewer system and subsequently to a publically-owned treatment works (POTW) where it is treated to secondary or tertiary standards prior to release. On campus storm and waste water treatment includes mostly primary treatment. Waste water from many laboratories is neutralized before discharge.

However, waste water from three kitchens is treated biologically before treatment using a mixture of five types of aerobic (3) and anaerobic (2) bacteria. The bacteria specifically target fats, oils, and greases discharged from these kitchens prior to release to the sewer and the POTW. This treatment program is being considered for use in even more kitchens during the next year.

The University uses CHEMSEARCH® which has developed state of the art DrainCobra™ and BIO-Amp™ Biological Delivery Systems to reduce and/or eliminate the accumulation of grease and organic buildup in drain lines and collection systems generated from food production, processing and preparation activities. Inadequate systems often utilized by kitchen facilities cannot handle the daily accumulation of excess fats, oils, and grease ("FOG") which can result in sewer line back-ups, excess costs for cleaning and removal of waste and potential fines or surcharges from local authorities.
